Tocll whom, it may concern:

Be it known that I, FRANK J..RussELL, a citizen of the 4United States, residing at New;

incandescent lamp plugs and extension cirelement.

' lngl ears.

cuit plugs, and possessing special utility as a sign receptacle for carrying the lamps em ployed in forming an electric light sign.

To this end the invention contemplates an improved electrical receptacle which may be characterized as a two-piece si n receptacle embodying telescopically an adjustably related members which provide for clamping the rece tacle 4bod directly upon the sign board p ate or ot er supporting l In this connection vthe invention has in view a construction of receptacle which can be iirmly secured to the supportin element Without the employment of screwoles or auxiliary fastening means While at the same time providing thoroughly eiiectual weather proof featurescso as to rotect the metallic arts from the action of t e weather.

A furtllier general object of the invention is to so construct an electrical rec tacle that the same shall possess considerab e strength so as to make the same 'better adapted to the strain of assembling than other forms of receptacles )articularly adapted for sign use, especially those having extended fasten- Also, the invention provides a receptacle of very compact construction and made-up of simple and durable parts which are so arranged as not to disturb or break the electrical connection by shaking loose Aas is `SOmetimes'the case with-other types of rece tacles.-

ith these and many other objects in view which will more readily appear as the nature of the invention is better understood, the same consists. in the novel construction combination and' relation of parts herein-.A

in the county of New York and after. more fullydescribed, illustrated and claimed., J

The essentlal features of the invention inv .ved in carrying out the objects above indicated arenecessarily susceptible to a wide range of structural modiiication without .de arting from the scope of the invention, ut certain preferred Dembodiments thereof are shown in the accompanying drawings in Which- 4 l Figure 1 is a front elevation, or fronti e'hd vievw. of a two-piece sign rece tacle constructed in accordance withv t e present invention. Fig. 2 is a rear elevation or end view ofthe receptacle. Fig.' 3 is a central longitudinal sectional view of the receptacle.

showing the various parts thereof. separated and illustrating their relation to eachother.

Fig. 5 isa side elevation of a modified vform ofthe receptacle Ashowing the complete housing of the line Wire terminal connections between lthe two cup members. Fig. 'is a longitudinal sectionalview of the form of receptacle shown in ',Fig. 15. Fig. 7 is an elevation of another modipatinn illustrating a variation in the' relativeslzes or proportions of the two cup members-constituting the body portion of the receptacle.

Like references designate corresponding parts in the several gures ofthe drawings A distinctive feature of the invention resides in the construction of the receptacle body whereby the same provides for carrying the various parts for the electrical conne@ tion While at the same time the body itself acts asa clamp for securing the receptacle upon a si n board plate or other supporting element esignated by the numeral 1 in the drawings. The said receptacle body consists essentially of two arts or members, namely, a pair of inner and) outer cup'members 2 and 3 made of porcelain, ber or other insulating material such as is commonly employed' in manufacturing fixtures of this character.

The inner and outer ou members 2 and 3 are adapted to adjustab yand telescopically'registerV one Within the clamp respectively upon opposite sides of the supporting element 1 which is provided therein with a receiving hole or opening 4 other, and to through which the receptacle body is inserted,- and exposed for the mounting of the elec- 'trical plug coarried by the lamp. To provide for an effective, non-rotative clamping sup portof the receptacle body on the element 1, the latter is preferably provided at one side of its hole or opening 4, with a laterally delcted retaining projection5 adapted to engage in a keeper notch 6 formed in one edge of the outer cup member 3 and held in such notch by a holding lug 7 projected from the inner side of an annular clam in collar 8 provided at the outer end of t e inner cup member 2 and presenting atits inner side a binding shoulder 9 which impinges against one side of the supporting element in opposition to the binding shoulder 10 presented at one end of the outer contact member 3, as plainly shown in Figs. 3 and 4 of thi. drawings. This provides, when the tw'o cup members are assembled and secured together, a self-sustaining clam for the receptacle body upon the supporting element 1.

The inner cu member 2 of the receptacle body is prefera ly provided with an integral insulatin bottom piece lltupon the outer side of w 'ch is supported the shell terminal or side plug contact l2 which is housed wholly within the plug receiving opening of the cup member 2. Preferably, the terminal or side plug' contact l2 consists of the -conventionalcthreaded metallic shell and may be secured in place in a thoroughly practical and electrical manner through the employment of an insulating button 13 arranged within the bottom of the contact or shell and pro; vided at one side with a shoulder projection 14 adapted to project through a base opening 15 in the bottom of the shell 12 and snugly register in a kee er. seat 16 formed in the outer side of the. ottom piece 11 of the cup member 2. The said button 13 is held in the position described by meansof the central plug contact and assembling screw 17 extending centrallyr` through. alined screw hoies in the button 13, the bottom piece 11 of the cup 2, and the integral bottom piece 18 of the cup 3. The head of the screw 17 engages with a contact washer 19 ex osed Within 4the plug receiving openin of t e receptacle, and the outer threade extremity of the said screw 17 engages a threaded opening 20 in a wire terminal plate 21 secured within a plate seat 22 channeled in the outer side of the cup bottom 18 and held in such seat by the ,securing screw 23. The said wire terminal plate 21 also carries a binding screw 24 exposed Within the plane of one of the pair of line wire grooves 25 formed in and extending transversely across the outer side ofthe cup bottom 18 as may be plainly seen from Figs. 2,l 3 andA of the drawings. The other Wire terminal plate. designated by the number 26, carries a binding screw 27 and therefore constitutes what may be termed a binding post secured directly to and carried by the plug contact or shell 12, said binding post being secured to the latter by means of a screw or equivalent fastening 28. The binding post 26-27 is anvularly arranged so as to bey readily projectedD through alined clearance openings 29 and 30 provided respcc tively in the cup bottoms 11 and 12 so that the binding screw 27 will be exposed in the other of said line wire rooves 25.

A. modification 'of tie invention is suggested in Figs. 5 and 6 of the drawings wherein the bottom piece 18 is illustrated as being entirely imperforate and the wire ter 'minal plate and its parts arranged upon the inside of said bottom piece 18 instead of upon the outside thereof. In this way the wire terminal connections are entirely housed between the bottoms of the two cup members, and to provide for the passage ofthe line wires the shell or wall part ofthe cup 3 is provided in opposite sides with the line wire receiving slots 3l.

A further modification is suggested in Fig. 7 wherein it is shown that the two cup menibers may be so sized or proportioned asto project'from opposite sides of the su porting element to any desired distance, an various other structural ino difications may obviously be resorted to without departing frem the s irit or sacrificing any of the advantages of t ie invention.

I claim- 1. In combination with a supporting element having a receptacle receiving hole and a retaining projection, an electrical receptacle having adjustably connected cup niembers clamped respectively upon o ipositc sides of the supporting element, sai niembers having respectively a cooperating notch and lug engaging with said retaining proj ection of the supporting element.

2. `An electrical receptacle comprising a pairof telescoping cup members provided with closed insulating bottoms, and one of said members being further provided with line wire passages, a wire terminal plate se cured to the bottom piece of the outer cup y member and having a binding screwv exposed to `one of the line wire passages, a side plug contact arranged Within the inner cup meme ber and carrying a binding post projecting through the bottoms of both cup members and exposed to the other linc wire passage, and a combined contact and assembling screw arranged to hold said side plug contact in position and adjustably engaging the wire terminal plate on the bottom piece of the outer cup member.

3. The combination with a supporting element, of an electrical receptacle comirising a air of cu members nested one wit iin the ot er and c am'ped respectively upon opposite 'sides of the supporting element, oneof l taets and-one of said Wire'conneotions, means wherebyl `one Contact serves to secure the cupmember carrying the other Wire terminal l vIn testimony Where-oil hereunto affix my signature in the presence of two yWitnesses.
